Oncology and Hematology Basics
Key Takeaways
- Febrile neutropenia: temperature in chemo patient with low ANC requires immediate cultures and antibiotics.
- Stop blood transfusion at first sign of acute reaction; keep line open with saline.
- Two-nurse bedside verification required before any blood product administration.
- Tumor lysis syndrome: hyperkalemia, hyperphosphatemia, hyperuricemia—hydrate and monitor closely.
- Bleeding precautions when platelets low: no IM injections, soft toothbrush, monitor stools.
Quick Answer: SNLE oncology-hematology items cover neutropenic precautions, chemotherapy side effects, tumor lysis syndrome, transfusion reactions, anemia, and bleeding disorders—essential for oncology wards and emergency recognition in general Med-Surg units across Saudi Arabia.
Oncology and Hematology Basics
Cancer incidence is rising with screening expansion in the Kingdom. Nurses must protect immunocompromised patients, manage chemotherapy toxicities, and respond to transfusion emergencies—content crossing adult acute and fundamentals infection control.
Neutropenia Precautions
ANC <500 (or institution threshold): private room when possible, meticulous hand hygiene, no fresh flowers or raw foods per policy, report fever immediately—febrile neutropenia is emergency (broad antibiotics within one hour per protocol concept).
SNLE trap: delaying blood cultures and antibiotics for temperature 38.3°C in chemo patient.
Chemotherapy Side Effects
| Effect | Nursing management |
|---|---|
| Nausea/vomiting | Antiemetics scheduled, not PRN only |
| Mucositis | Soft diet, oral care, analgesia |
| Alopecia | Psychosocial support, scalp cooling if available |
| Extravasation | Stop infusion, aspirate, antidote per drug |
Tumor lysis syndrome after chemo for bulky tumors: monitor K+, phosphate, uric acid, calcium; hydration, allopurinol/rasburicase per order.
Radiation Nursing
Skin care: gentle washing, no powders in field, sun avoidance. Fatigue and diarrhea when abdomen radiated—symptom management.
Blood Transfusion Reaction
Stop blood, keep line open with saline, notify provider, vital signs, send blood bag and labs. Acute hemolytic: fever, chills, back pain, hypotension, dark urine. Febrile non-hemolytic: fever without hemolysis—slow or medicate per protocol.
Always verify two nurses at bedside: patient ID, blood unit number, type, crossmatch.
Anemia and Thrombocytopenia
Fatigue, pallor—transfuse per hemoglobin threshold. Platelets low: bleeding precautions, no IM injections, electric razor, monitor stools for melena.
Coagulation Disorders
Hemophilia: avoid trauma, factor replacement per order. DIC: bleeding and clotting simultaneously—treat cause, support with products per ICU.
Palliative and End-of-Life
Pain control, spiritual support respecting Islamic practices, family presence, do-not-resuscitate orders per Saudi legal framework and hospital policy—comfort care without abandonment.
Worked Scenario
Chemo day 10, ANC 200, temp 38.5°C. Blood cultures x2, broad spectrum antibiotics stat, monitor BP—do not wait for morning rounds.
Traps
- Live vaccines to immunosuppressed
- Restarting stopped transfusion after mild itch without provider
- Missing TLS labs after initiating chemo for lymphoma
Final Check
Define febrile neutropenia response, transfusion stop steps, and two chemotherapy mucositis interventions.
